Application

Can be used as a damp proof base for renders, plasters or dot and dab plasterboard and a damp proofing system to deal with rising damp.

Suitable for wall finishes including:

  • Plaster.
  • Render.
  • Hydraulic lime.
  • Plasterboard bonded to the membrane with a propriety adhesive compound.

Description

BBA certified damp proof membrane, comprising of high density polyethylene membrane with a rot-proof polythene mesh that is heat-welded during the manufacturing process to the surface of one side. The meshed surface creates a mechanical key to allow the membrane to be plastered, rendered or to receive dot & dab plasterboard.


Features and benefits:

  • Provides a surface that is totally separated and unaffected by the dampness within the wall ensuring that the wall finish will never be affected by moisture or salts.
  • Superb ‘key’ for renders or plasters.
  • No need to use injected damp-proof courses which unnecessarily pump chemicals into the property.
  • Completely moisture resistant but allows vapour diffusion.
  • Quick and easy to install.
  • In many cases, the existing render can be left on the wall.
  • No requirement for damaging preparation to the wall surface.
